The annual running of the bulls at this famous festival is making a few PETA protesters stand up against the brutality of the festival. They stripped off and drenched themselves in blood to protest.

The group of protesters at Pamplona, Spain, are making a stand against the San Fermin bull run by stripping off their clothes and covering themselves up in fake blood.

It's a demonstrate for the abolition of bull runs and bullfights a day before the start of the famous running of the bulls.

The bulls are killed after the traditional event. "It is a cruel, violent and bloody way for bulls to be executed," said Kirsty Henderson, animal rights group PETA's campaign director for the festival.

"We will have 54 activists stand in the town square each holding a bucket of fake blood, wearing briefs but nothing on top, and on cue they will pour the blood over their heads," Henderson added.

The activists will represent the number of bulls expected to die in the ring at this year's festival. Which means around 54 bulls are expected to be killed.
